Embodiment
[0020] The amount of domestic sewage in a community is 300 tons / day. The water quality indicators of the sewage before entering the water treatment system are: COD=280mg / L, BOD=150mg / L, ammonia nitrogen=35mg / L, SS=180mg / L. Sewage is treated sequentially through an aeration regulating tank equipped with suspended fillers, a pressure bioreactor and a pressure filter. The effluent water quality indicators of the device are: COD≤30mg / L, BOD≤5mg / L, ammonia nitrogen≤0.8mg / L, SS≤5mg / L, the effluent water quality meets the national sewage recycling standard, and can be reused for flushing toilets and greening after disinfection.
